#3787: GHC 6.12.1 panic
-------------------------------+--------------------------------------------
Reporter: blamario | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Compiler | Version: 6.12.1
Resolution: | Keywords: panic
Os: Linux | Testcase:
Architecture: x86_64 (amd64) | Failure: Compile-time crash
-------------------------------+--------------------------------------------
Comment (by ajd):
This also happens on i686. Note that it only happens with optimizations
enabled (-O or -O2).
I trimmed down the module as much as I could while preserving the bug;
I'll attach the result. Note that removing the type signature or any of
the cases of resolveProducerConsumer makes the bug go away: all four must
be present to cause the panic.
